Röhrchenset

Röhrchenset is a term used in laboratory contexts to describe a ready-made kit consisting of small tubes, often microcentrifuge tubes, designed for handling and processing small-volume samples. The set typically includes a collection of tubes in a common rack, with screw-cap or snap-cap closures, and may come with labeling, a storage stand, or additional accessories. Tubes are usually made from chemical-resistant polymers such as polypropylene and are intended to withstand routine laboratory use.

Common sizes in a Röhrchenset are 0.5 mL and 1.5 mL, with some configurations including 2.0 mL tubes. Tubes feature conical bottoms to help recover contents and enable efficient mixing and centrifugation. Many sets offer sterile, DNase- and RNase-free options for molecular biology work, and caps may be color-coded to aid organization.

Typical applications include sample storage and aliquoting, preparation for enzyme reactions, polymerase chain reactions (PCR), DNA/RNA extraction steps, and general handling of small volumes in laboratory workflows. The tubes are designed to be compatible with standard microcentrifuge rotors and, depending on the material and manufacturer guidelines, may be autoclaved for sterilization.

Standards and care: Röhrchensets often specify chemical resistance and temperature tolerance appropriate for common lab environments, including freezing and autoclaving where applicable. Some sets are certified sterile, while others are non-sterile; users should verify integrity, labeling, and compatibility with their equipment and reagents. Proper storage, cleanliness, and avoidance of cross-contamination are recommended practices.

Origin and usage notes: Röhrchenset is a German-language designation for a ready-to-use collection of small tubes, with contents and configurations varying by supplier and intended application. Similar products are sold worldwide under various brand names.
